I had LocomotiveCMS on my radar for quite a while as it looked very promising, but lost track as development staggered for a year or so.
Do you use their hosted solution or do you host it on your own servers? Do you have any information if the version on Github[1] differs in significant ways from the hosted solution?
It seems like they are really pushing the hosted solution now, their website doesn't make it very clear that you can install it by yourself too.
